Answer:
7.17%
Step-by-step explanation:
For determining the weighted average cost of capital first we need to find out the after cost of debt and cost of preferred stock and the cost of common equity which are as follows
Cost of debt is
= Yield × (1 - tax rate)
= 7.5% × (1 - 40%)
= 4.5%
Cost of preferred stock is
= Dividend ÷ price
= 8 ÷ $96
= 8.33%
And, Cost of common equity is
= risk free rate + beta × market risk premium
= 3% + 1.2 × 5%
= 9%
Now the weighted average cost of capital is
WACC = cost of debt × weight of debt + cost of preferred stock × weight of preferred stock + cost of common equity × weight of common equity
= 4.5% × $80 ÷ ($80 + $10 + $110) + 8.33% × $10 ÷ (80 + $10 + $110) + 9% × $110 ÷ ($80 + $10 + $110)
= 7.17%
